A structure that fills with sound and acts as a natural amplifier.
Industry:Natural environment
Activities undertaken by humans to repair ecological damage, such as establishing vegetation on degraded habitat, increasing the populations of endangered species, and decreasing the threatened area of an ecosystem.
Industry:Natural environment
An isolated flat-topped coral reef which reaches the surface but lacks a lagoon.
Industry:Natural environment
Cell eating. A process in which phagocytes engulf and digest microorganisms and cellular debris; an important defense against infection .
Industry:Natural environment
High-energy radiation capable of producing ionization in substances through which it passes, i.e., radiation that has enough energy to eject electrons from electrically neutral atoms, leaving behind charged atoms or ions; examples are alpha particles (helium nuclei), beta particles (electrons), neutrons, and gamma rays (high frequency electromagnetic waves, x-rays) .

In taxonomy, when two different names for the same taxon are first published in the same publication, then the one which appears on the earlier line has line precedence. Line precedence does not necessarily mean priority as well. This is determined by the action of the first reviser.
Industry:Natural environment
The evolution from one species of organism into a number of different species. As the original population increases in size, it spreads out from its center of origin to exploit other habitats and ecological niches. In time, this results in a number of populations, each adapted to its particular habitat. Eventually these populations, genetically may differ from each other sufficiently to become new species. Divergent evolution has also been termed "adaptive radiation".
Industry:Natural environment
The probability, based on statistics, that a number will be between an upper and lower limit.
